Abstract: A method and apparatus for producing a 3-D image file. In a preferred embodiment, the 3-D image file is produced using a source including a set of graphics instructions. The source data is produced, for example, by translating a data set into graphics instructions by a translation application. The graphics instructions are then converted into movie file commands by a graphics converter. In a preferred embodiment, the graphics instructions are converted by a set of procedures which contain storage and display information for each of the graphics instructions. Each command corresponds to a specific graphics instructions, and contains information for instructing a display software application to display a characteristic of a 3-D image. The commands are then recorded in the output 3-D image file.

Abstract: An exhaust manifold catalytic reactor and muffler for an automotive internal combustion engine includes at least one exhaust branch for conducting exhaust gases from the cylinder head exhaust ports of an engine to a hollow, generally cylindrical primary catalyst substrate for treating the exhaust gases flowing from the engine. The substrate has inner and outer surfaces which are generally cylindrical and which define an inner cavity. A housing connected to the exhaust branch places the exhaust gases in contact with the substrate and includes a generally cylindrical container having an outer wall and a transition section conducting the exhaust gases from the branch to the outer surface of the substrate such that the initial flow of the gases from the branch to the outer surface of the substrate such that the initial flow of the gases from the substrate is generally tangential.
